Abstract

L'invention concerne un procédé et un dispositif servant à maintenir les niveaux de puissance d'un signal reçu à un niveau moyen quand une estimation de puissance de signal est en moyenne similaire à la moyenne des niveaux de puissance d'un signal réellement reçu (P(n)). Le maintien des niveaux de puissance du signal reçu est effectué par génération d'une estimation de la puissance d'un signal reçu. Ensuite, un signal de différence est généré par la soustraction de la puissance estimée du signal reçu de la puissance prédéterminée d'un signal de référence (Pref). Enfin, un seuil de commande de puissance de signal est ajusté en fonction du signal de différence (106).
